From Dragon Quest Wiki

Kathwack is a recurring spell in the Dragon Quest series.

It attempts to kill all enemies outright with a macabre incantation, and is the ultimate form of Whack and Thwack.


Dragon Quest IV: Chapters of the Chosen remakes[edit]

Kathwack is learned by the 9th Chosen One at Level 42.

Dragon Quest V: Hand of the Heavenly Bride[edit]

Conkjurers try to use this spell in battle but always fail due to lack of MP.

Dragon Quest VI: Realms of Revelation[edit]

Kathwack is learned by mastering the Sage vocation, and costs 15 MP.

Dogmus also casts it.

Dragon Quest VII: Fragments of the Forgotten Past[edit]

A variety of vocations teach Kathwack: Druid at rank 2, Black bishops at rank 4, and rank 6 of the Bone baron. It costs 15 MP to cast, as usual.

It can be cast by the enemies Conkjurer, Infernal kernel, Dark decanter, and Hirsute hexer, although Conkjurers lack the MP to cast it.

Dragon Quest VIII: Journey of the Cursed King[edit]

Angelo can acquire the spell by investing 56 points into his Staff skill and costs 15 MP.

It can be cast by the enemies Unholy bishop, Trap Box in Memoriam, and Marcello in Memoriam.

Dragon Quest IX: Sentinels of the Starry Skies[edit]

Kathwack is learned by Priests at Level 55, and costs 20 MP to cast. As with the other Whack spells, it's potency is reliant on the Priest's Magical Mending, raising the base accuracy from 75% at 200 to 100% at 799.

Dragon Quest X[edit]

Kathwack is a spell exclusively used by monsters, and it costs 20 MP.

Dragon Quest XI: Echoes of an Elusive Age[edit]

Serena learns Kathwack at level 63, and it costs 20 MP with a 75% base accuracy against non-resistant monsters. As it cannot be learned by Rab and Serena has zero Magical Might growth period, the benchmarks for the spell are among the lowest in the game: Kathwack will rise to 85% accuracy at just 200 Magical Might.

Dragon Quest Heroes & Dragon Quest Heroes II[edit]

Kathwack appears as Kiryl's Coup de Grâce, carrying over from Dragon Quest: Monster Battle Road. After trying and failing to cast Thwack multiple times, Kiryl becomes annoyed and stomps on the text windows in frustration, before casting a souped-up version of Kathwack, which annihilates groups of enemies with waves of darkness. This version of Kathwack causes damage, rather than instant death. This references Kiryl's AI in the NES version of Dragon Quest IV, where Kiryl would infamously cast the Whack and Thwack spells constantly against boss monsters to no effect.
